Nah…most brands say the aero benefit of wheels is minimal once you get to 40+mm in tire width.
With 28-32mm tires, the 3.4 is going to deliver a wattage savings of up to 10 watts at 20 mph over the G23 with the same tire. That doesn’t tell the entire story, however. As tire width increases beyond 32mm, the 3.4’s aero advantage diminishes. Going up to a 40mm tire, the two wheelsets would essentially be aerodynamically equal.
